To all whom it may concern:

Be it known that I, ANTHONY L; CIHAK, a citizen of the `United States of America, and a resident of Waterloo, Blackhawk county, `Iowa, have invented certain ynew and useful improvements in Gasitpparatus,u

of which thefollowing is a specification.

lily invention relates to improvements in gas apparatus, and the object of my improvement is to provide new and useful automatic regulating devices for governing the supply and pressure of theair supplied by the machine to the carbureter. rThis object have accomplished ,by Vthe mechanism which is hereinafter described and claimed, and which is fully illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of an airpump for forcing a supply of airunder pressure to the carbureter, with my improved regulating devices embodiedtherein. Fig.

'2 1s an enlarged axialsecti'on of the valvechambers with their communicating pipes and the inclosed valve mechanism. Fig. 3 is an enlarged detail elevation, partly in section, of the water-pump and its connections. Fig. 4 is an enlarged detail of the said improved automatic governing apparatus.

Similar numbers refer to similar parts throughout the several views. l My improved governing device is an integral partof the mechanism of a gas apparatus for the control of the air pressure in the carburetor. The pipesi37-K38 communicate between a carbureter (not shown) and the interior of an inverted bell 35, the latter being immersed in water contained in a receptacle `3G, vwhereby an airspace is formed in the bell over thewater-seal, by air issuing from the open upperend of a pipe 34. rlhe vertical pipe 84 passes down through the bottom ofthe receptacle 86, where it is connected with a short horizontal pipe, and the latter with ariser 33V extending into the second receptacle 30, with its openupper end above the water-level of a water-seal therein.' Another riser pipe 81 passes through thebottom of the receptacle 30, with its upper end above the water-level, its outer end connected to a horizontal pipe 32, which is an air-inlet for the verticallymovable bell 57 the latter having its lower end inserted in the water in the receptacle 30.VV The upper ends of `each of the pipes 31 and 34 are supplied with valves which open and close respectively accordingly as the movable bellV 57 rises and falls under theimpulse `thereby given to the air under both said bells.

rEhe frame 27, supports the mechanism of a water-pump, whose cylinder 6 contains a solidpiston 40 secured on the'lower end of a Diston-rod 7, the latter working through the upper cylinder-head 59, with its upper end secured in a cross-piece 39. From either'l end of said cross-piece depend fixed rods 8 and 48 whose lower ends are secured to the ends of another 'cross-piece 49, which has a central depending eye-bolt 28 secured to the center of the top `of the bell 57.

A rod 23 whose upper end is slidable through an eye-bolt 56 secured tothe frame 27, has aweight 25 on its lower end adapted to contact with the upper end of the bell 35, to exercise a downward pressure o-n the latter, and which tends to regulate the motion of said bell by preventing any sudden or jerky movements thereof which otherwise might be caused by reason of the air impulses derived from the mechanical action of the bell 57. Y

Y rIwo collars 9, spaced apart, are adjustably seated about the lower part of the rod 8 by meansof set-screws, and their inner ends are provided with hemispherical rubber caps,

said collars forming stops for the end ofthe lever 50, the latter being slidably secured about said rod between said stops by means of a yoke 51.v The rods 8 and 48 moveA `through the eye-bolts 55 on the frame 27.

. The numeral 1 designates a pipe in communication with any suitable source of waterhead, andk is coupled to a horizontal pipe 3 containing a cut-off valve 2. T he latter pipe is in communication with the valve-chamber 4. A pipe 5V affords communication between said valve-chamber and the pump-cylinder 6, while the pipes 24-26 alford an egress to exhaust water escaping from the valvechamber. Y

VThe valve-chamber 4 has lateral tubes 61 and V62 projecting in opposite directions, of which 61 is exteriorlythreaded to enter the pipe 8, while the tube 62 isv interiorly threaded to receive the end of the pipe 24. By this arrangement the valve 41 which is of conical form, moves in the line of water pressure against the end of the tube 61 as its seat-,while the exhaust-valve 42 is located within the tube 62 and moves in the line of water pressure against the end of the pipe tion thus results on the Valves 41-42 in l rllhe two valves their to-and-tro movements. are therefore both so placed that when closed the water-head acts with 'them instead o1' against them, thus more eiilectively sealing,- the openings at their seats.

The nunie al 13 designates a rock-shaft seated in bearings in said valve-chamber and projecting` therefrom, and roch-arms 47 being` secured thereto within said chamber. r Valve-stem 43 has its bent inner end pivoted at 44 to one of said roch-arms, while the valve-stem 45 of the other valve 42 has its bent inner end 46 pivotally connected to the end of the other rock-arm 47. shaft 13 is rocked in one direction, by this means the valve 41 is retracted from its seat permitting the entry of water under head 1 from the pipe 3 to the chamber 4, wnile the exhaust-valve is at the same time iirmly pressed against its seat. A reverse rocking of said shaft causes a reversal of the above action, by closing the inlet-valve 41 against its seat, and openingthe exhaust-valve allowing` egress to the pipe 24 of the water in the chamber 4 and below the piston in the cylinder 6. rl`he automatic controller for aid'rocl-shaft 13 is shown in Figs. 1 and 4. The lever 50, whose outer end embraces the rod 8 between its fixed collars 9, has its inner end pivoted on the roch-shaft 13 outside of the valve-chamber 4.

arms o1l a bell-crank lever pvoted on said rock-shaft 13. r1`he lowermost shorL member of said lever has secured transversely thereto at its ends at a medial point a cross-bar whose ends are bent rearwardly at right-angles and adapted to be contacted by the pivoted arm 50 respectively when the latter is shifted either up or down, by the upward or downward movement ot its connected rod 8. rlhe longer uppe member 10 of said bell-crank lever at its ipper end a slidable cylindrical weight 18 adjustably secured thereon by a set-screw. Just below said weight a cross-bar 14 is slidably and adjustably secured to said member 1G by a set-screw A straight crossbar 20 has its ends mounted in seats in the downturnedends of the cross-bar 14, and slidable collars 54 and 52 are adjustably s1- cured on it near its ends by means ot setscrews. A cylindrical reight 15 is adapted to. slide upon the cross-bar 20, and to said weight is connected ene end of a short chain.

17 whose other end is connected to the outer end ot a lever-arm 12 which 1s secured to the W hen the l ias outer end of the rock-shaft 13. A slidablc weight 1G is adjustably secured upon the arm 12 by means of a set-screw.

A 'ined vertical upright 22 extends up ward from the valve-chamber 4, and a short chain 21 is connected between it and the eye 19 on the upper end of the bell-crank incinber 10. This upright 22 is made slightly resilient, which diminishes the shock due to tne falling` o1" the weighted member 10 oit said bell-c `anlt lever.

The conical-valve heads 41 and 42 are iro ordinarily `constructed' of y rubber or similar yielding material;` in Yorder to insure a close t between themselves and theirA seats. The wear ony their contact-surfaces is taken up so as to keep the said fit perfect by this adjustment of the cross-bar 14: on tliearm 10. rThe chain connected between the' upright 22 and the member lOIlimits the movement of said member in either direction, and takes o the shock of the sudden fall .of the weight l5 Lfrom theother parts.V Thel arm 12 may also be adjusted in its position on the rock-shaft, so `as to set the valves in the proper positions to insure their fitting their seats. The weight 16 on the arm 12Vis made suficiently massive to'liold the valves ,lll and l2 securely in place against their seats, compensating for slackness in the bearings which may be occasioned by wear.
